Feed plates for typewriters or the like



Nov. 17, 1959 E. A. G. HEDENSTROM 2,913,094 FEED PLATES FOR TYPEWRITERS OR THE LIKE Filed March 25, 1957 mvqzy'ron Anders G Hedensfram ATTORNEYS United States Patent 2,913,094 FEED PLATES FOR TYPEWRITERS OR THE LIKE Erik Anders Gustav Hedenstriim, Bromma, Sweden Application March 25, 1957, Serial No. 648,343 2 Claims. (Cl. 197-133) This invention relates to feed plates adapted to be positioned at the rear or infeed side of the platen of a typewriter or the like so as to extend upwardly and rearwardly thereof to form a substantially smooth surface over which the sheets or webs to be typed are fed to the typewriter.

The sheets or webs to be typed are commonly interleaved with carbon transfer sheets and as the assembly is fed over the feed plate there is tendency for the sheets or webs to wrinkle or buckle so that they do not lie flat on the front face of the said plate with the result that they will not always be fed correctly to and around the platen. This is particularly true where the sheets or webs are divided into connected lengths by longitudinally spaced transverse fold lines, since the sheets or Webs tend to buckle outwardly at said lines.

It is an object of the present invention to provide means for ensuring that sheets or webs will be pressed against the front of the feed plate so as to be maintained in the fiat unbuckled condition as they are fed to the platen.

According to the present invention an elongated member is provided on the feed plate, the member having its upper end secured at or adjacent to the upper end of the feed plate and extending downwardly over the front face thereof, the member being adapted to rest on the webs or sheets being fed over said plate so as to press them against the latter.

To enable the invention to be fully understood it will now be described with reference to the accompanying drawing, in which:

Fig. 1 is a front view in more or less diagrammatic form, illustrating one embodiment of the invention; and

Fig. 2 is a section on the line 2-2 of Fig. 1.

As shown in the accompanying drawing a paper supporting plate 1 is positioned at the rear or infeed side of the platen 8 of a typewriter and extends upwardly and rearwardly therefrom. The plate is provided with an integral flange 2 on each side edge which serve as lateral guides for paper sheets or webs 3 as they are fed over the feed plate to the platen around which they are drawn during the typing operation.

At the upper end the feed plate is provided with a plate 4 at each side, which plates serve for detachably supporting a cross member in the form of a rod 5 which extends transversely of the plate 1 at the upper end thereof and in spaced relation to the adjacent portion of the plate 1 over which the paper sheets or webs are fed.

A flexible member in the form of a chain 6 has its upper end detachably secured at the center of the rod 5 and as shown, extends downwardly over the front of the supporting plate. The lower end of the chain has a lower end member in the form of a cylindrical member 7 secured thereto which extends along substantially the entire width of the feed plate. The arrangement is such that due to the weight of the chain and the cylindrical member 7, they will be automatically caused by gravity to press against the sheets or webs 3 so as to maintain them in a flat condition as they are fed and prevent any tendency for them to buckle or move away from the feed plate.

Having thus described the invention, what is claimed as new, is:

1. In a typewriter, bookkeeping machine or the like having a platen for feeding paperstformed in webs, a device comprising a paper supporting plate, said plate extending upwardly and rearwardly of the platen, the paper webs being fed downwardly over the plate by the platen, said plate having side flanges thereon, a cross member extending between the side flanges on said plate above the upper edge of said plate to permit passage of the paper webs beneath said cross member and over the upper edge of said plate, and a single elongated flexible member extending downwardly from said cross member, said flexible member having a lower end member at the lower end thereof extending across said plate parallel to the platen and spaced above the platen, whereby said lower end member will rest against the web of papers being fed downwardly along said plate by the platen.

2; A device as claimed in claim 1 in which said flexible member is a chain and said lower end member is a cylindrical bar.
